As the climate changes, drought is worsening across large swaths of the globe. To combat this, a team of Princeton researchers is looking to an unusual water source – the air. The team aims to use thermo-responsive hydrogels, or networks of polymers that are commonly used in biomedical applications, for water harvesting.

Yeast already helps make bread and beer and cranks out the biofuel ethanol, but scientists believe it can be used to create an even more efficient fuel called isobutanol. Normally, yeast only creates a tiny amount of isobutanol. Now researchers at Princeton University have discovered a genetic switch that significantly ramps up production.

A team from Princeton University and Ohio State University has been awarded a five-year, $3-million grant from the U.S. Department of Energy to advance research on low-temperature plasmas.
